CATHI conducts cognition checks

This friendly robot listens, speaks, watches, and analyses during an assessment

Illnesses such as dementia are becoming more prevalent in an ageing population. Treatment is more effective for these debilitating conditions when they're detected earlier, but busy doctors don’t have time to perform significant numbers of screenings.

Come and meet CATHI - Cognitive Assessment Through Human-Robot Interaction. You’ll see a robotic medical health technician who listens, speaks, and watches while presenting and analysing an industry-standard cognitive test.

The potential is to make initial screenings available at medical centres as straightforward as getting your blood pressure checked. For the patient, it’s a more friendly and reassuring experience than an abstract online assessment. For the doctor, it’s a way to concentrate on those identified as needing a full cognitive assessment.

Sheffield Hallam University worked with an IBM Senior Inventor and Visiting Research Fellow from Hursley's Innovation Centre to enhance their Cognitive Assessment Robot project. They used IBM Watson Visual Recognition for analysing drawings, plus Speech to Text, Text to Speech, and Watson Assistant for expressive natural discussions.

The design and development team won an award earlier this year from the International Federation for the Promotion of Mechanism and Machine Science, in recognition of significant achievement in Medical and Service Robotics.
